Ca reactor

[super7]

What is the purpose of adding CO2. Is it definately needed.
Thanks Super7
I am a newb concerning Ca reactors

CO2 lowers the pH of the water within the reactor chamber, thus slowly dissolving the media.

[super7]

is there another way of lowering the pH of the water within the Chamber.
Thanks Super7

Not that I have heard of.

the problem with me using CO2 is I don't know where to put the cylinder of CO2. I now know how the Ca reactor works. Would dosing kalk work, the tank is only 75 but I am looking at enlarging the system by adding another tank. So there will be about 100 gallons of water.
Thanks Eric

Kalk works as well as other Ca supplements.

Back this up a bit, what are you keeping, as in do you even need a reactor? Are you now measuring your Ca levels and how much is being depleted daily/weekly?

I am planning for the future as I will be keeping hard corals also since I sell marine merchandise I like to kow how it works. Meaning I like to make one for myself then use it. My system that I am thinking about has only been running two months roughly.
Thanks Eric

Does a kalk reactor do the same thing or is it the same thing/.

Different than a Ca reactor but similiar in that they both add Ca. No CO2 bottle required.
